This invention relates to improvements in tobacco ipes, and an object t ereof resides in rovi 'n means to prevent clogging or t fo ing of t e tobacco at the bottom of the '5 bowl of-the pipe and to thereby enable they bowl, the construction and operation of this j extra movable bottom being such that it may be forced upwardly as a piston against the tobacco and then downwardly to 4leave a free air space between the movable bottom and the displaced tobacco, thereby preventing com-` paction ofthe tobacco into a substantially wad like form which interferes with the free passage of air and smoke through thepipe. It 2 is found in practice that the air space referred to allows space for the swelling or expansion of the lower layers of the tobacco and in this manner overcomes the objectionable compacv tion referred to. The construction of the movable bottom is such' that the latter may be removed from the pipe for cleaning and other purposes and, moreover the bottom is applicable for ready employment in connec- 36 tion with ordinary tobacco pipes.

perforating the vmovable false bottom of the pipe bowl and wherein the bottom is formed with a movable hinge stem, the actuating porn tion of said stem being received within a re- 5 cess formed in one of the exterior surfaces of the pipe bowl when the false bottom is normally positioneds the arrangement being such that the stem may be removed from said reo cess and caused to assume a perpendicular position in registration with the axis of the bowl, whereby the stem may be readily grasped and reciprocated by a simple manual operation to move the false bottom vertically or axially of the bowl. v

With these and other objects in view, whichA will appear as the descriptionproceeds, theV invention consists in the novel features of v construction, combination of elements and 0 arrangements of parts hereinafter fully de-v Another object of the invention resides in scribed and pointed out in the appended clalms.

In the drawings:

Fig. 1 is a vertical sectional view taken throu l1 a tobacco'pipe formed in accordance 55 with t e present invention;

Fig. 2 isa bottom plan view thereof;

Flg. 31s a perspective view of the movable false bottom and its associated operating link and F1 4 is a transverse sectional view on the line of Fig. 1.

ln the drawings, wherein for the purposes of illustration, is shown the preferred embodiment of the present invention, the numeral 1 a5 -designates generally a tobacco pipe of any well known construction, the same including the usual bowl 2, the stem 3 anda mouth piece 4. In the present instance, thebottom of the bowl 2 is provided with an axially arranged 70 opening adapted for the reception of a slightly tapered sleeve' 4 which issecurely fitted within said opening against accidental displacement. Arranged to be positioned within the sleeve is a tapered stem 5 and formed with 75 or secured to the upper end of the stem 5 is a movable false bottom 6 of the tobaccov bowl. Preferably, the sleeve 4, the stem 5 and the bottom 6 are formed from metal' although other suitable materials used in pipe manufacture may be utilized.

. The movable bottom 6 is preferably of concavo-convex cross sectional formation and is of slightly smaller diameter than the inner diameter of the pipe bowl. The bottom may be perforated or not, as indicated at 7, and is ordinarily positioned in the lower portion of the bowl, as shown in Fig. 1., Preferabl the lower surface of the bottom 6 is provide with an annular groove Iindicated'at 8 desi ed 90 for the reception of the upper edge o the sleeve 4 which in conjunction with the tapered form of the stem 5, provides for a v double seat of the opening formed1 in the bottom of the bowl to prevent undue escape of 05 `fluids from the pipe bowl in channels other than that provided bythe main assagew-ay 9 of the stem 3. The location of t e sleeve 4 is such that when the bottom 6 is normally ositioned, the same will be disposed in a p aneslightly above that of the passageway 9 in or er that the false bottom will not interfere with the desired passage of smoke through the pipe. I preferably use a ring 10 of an yabsorbent material such as cotton or fabric below the false bottom and' around that portion of the sleeve 4 which rejects into the bottom of the bowl, in or er that the absorbent material will retain liquids or oils developed by the burning of the tobacco and to prevent the passage of such fuels through the main stem 3 of the pipe.

The lower ortion of the stem 5 is pivotconnectetl as at 11 with an operating lin 12. When the pipe is in use, the link 12 occupies a longitudinally extending recess 13 formed in the lower exterior surface of the pipe bowl and the stem 3, in order that the link 12 will lie iiush with the exterior surfaces of the pipe and will not in any way interfere with or mar the general configuration thereof. The link is preferably provided at a point midway of its length with a depression 14 which receives a convex enlarge- `ment 15 formed in connection with one of the side walls of the recess 13, whereby the link is positively locked or retained in its folded or inactive position in said recess.

In operation, the false bottom 6 is positioned as shown in Fig. 1 and the link 12 is folded to lie within the recess 13. Tobacco -smoked in the usual manner.

is `then placed in the bowl of the pipe in the usual manner, as indicated at 16, the tobacco being pressed downwardly within the bowl until it securely engages with the bottomp. The tobacco is then ignited and the pipe The smoke may pass through the perforations 7 provided in the false bottom, thence throu h the ring of absorbent material and nally through the passageway 9 to the mouth of the smoker. If the tobacco has been too firmly tamped into the bowl during the filling operation, this condition may be relieved by rocking the link 12 to the vertical dotted line position disclosed in Fig. 1, and by a plying upwardly directed pressure to tlie link, the false bottom may be raised to move the body of tobacco in the bowl 2 upwardly for a slight distance. The false bottom is then restored to itsnormal position which results in leaving a slight air space between A the upper surfaces of the false bottom and the body of tobacco in the bowl 2. By this operation, the body of tobacco is loosened suiiciently to provide for the free passage of air and smoke therethrough and the alr space produced in the base of the bowl also facili- The burning of tobacco frequently generates oils and liquids, and -by utilizing the absorbent material 10 around the stem and guarding the entrance to the passageway 9, a convenient means is ro vided for preventing such liquids Prom reaching the mouth ofthe pipe user. This ring of absorbent material may be replaced from time to time. Thus, by virtue of the construction described I have provided a pipe capable of producmg at all times a cool ry smoke. The false bottom mag be cperated to remove ash and partially urne tobacco from the bowl in an effective manner so that it is unnecessary to use extraneous scraping and cleaning tools. Due to the construction of the falsecbottom and the provision of the absorbent ring, it is impossible for slugs or small pieces of tobacco to enter the mouth and this feature is particularly advantageous when dr or small pieces of tobacco are being smo ed.- As stated, the absorbent material takes up the oil released by the burning of tobacco and by its position in the base of the pipe bowl,'the absorbent may be easily removed and other rings substituted from time to time. By reciprocating the false bottom, the tobacco can be positively ejected from the, bowl avoiding completely the digging and scraping operations heretofore involved in the removal of ash and charged tobacco from pipe bowls.

The link 12 is of such diameter that it passes freely through the sleeve 4 so that the entire false bottom together with its pivot link may be removed from the pipe through the open upper end of the bowl. Preferably, the link 12 is of such length with respect to the height of the bowl that in replacing the false bottom with the link 12 hanging perpendicular therefrom, the extreme lowerend of said link may then be manually guided into the enlarged upper end of the sleeve 4 so that by releasing the false bottom or disk 6, the latter will drop into the bottom of the bowl and the link 12 will project below the bottom of the bowl as shown by dotted lines in Fig. 1. Then by oscillating the link around the pivot 11, it may be restored to its inactive position within the recess 13 and positively locked therein. I am aware of the fact that it has been proposed heretofore to provide tobacco pipes with movable false .visioned for completely removing through the open upper end of the pipe bowl, the ejector means as herein disclosed.

The construction of my pipe is essentially simple and does knot involve any change in standard pipe design. In fact, the construction may be embodied in any of the standard forms of tobacco pipes now in general use.

While I have described the construction comprising the preferred form of my invention in considerable detail, it will be understood however that variations may be made herein without necessarily departing from the scope and spirit of the invention as the latter has been vdefined in the following claims.

What is claimed is: 1. In a tobacco pipe, a tobaccoreceiving bowl having a smoke outlet in the bottom y thereof, a tapered sleeve stationarily positionedlin an opening formed axially in the lower wall of said bowl, the upper end of said sleeve terminating above the bottom surface of the bowl, a perforated bottom member slidably mounted in said bowl, a stem formed with said bottom member and normally received within said sleeve, said bottom being adapted to engage with the upper end of sai sleeve whereby to maintain said member in spaced relation from the bottom of said bowl and the smoke outlet leading therefrom, and a linkivotally connected with the lower end of sai sleeve and normally adapted to occupy a longitudinally extendlng recess formed in one of the exterior surfaces of the bowl, said link being so proportioned as to pass freely through said sleeve when in vertical alignment therewith.

2. In a tobacco pi e, a bowl formed with a tobacco receiving c amber having a smoke outlet in the lower portion thereof, said bowl being further formed with an axial opening in the bottom of said chamber, a sleeve positioned in said latter opening and having the upper end thereof terminated within said 3o chamber above the bottom o'f the latter, a perforated disk movable up and down in said chamber and having an annular groove formed in its upper surface arranged to receive theupper edge of said sleeve when the disk is positioned on the sleeve, the portion of the sleeve proJecting upwardly into said chamber constituting a centering stud for the reception of a removable ring of an absorbent material, a stem formed with said disk and 40 receivable within said sleeve, and a link pivoted at one end to said stem and said link .be-

ing proportioned for free passage through said sleeve, said link when inactlvely positioned being disposed within a longitudinally extending recess provided in the lower exterior surface of said bowl. c In testimony whereof I aix ature.
